The 4 Artifacts are mysterious objects shaped like Magatamas left behind by unknown species, scattered around Sirius. Being that there are only 4 of them, each with their own colours (Green, Red, Blue and Black), they are extremely rare and not many people know about them.
It is unknown when, how and why do they exist. All that is known is that it glows near Nomadic entities, it is invisible in our Cargo Scanning devices and the radiation warning device in most ships never stop blinking, should the Artifact be inside the ship.
The first of these Artifacts was discovered in 816 A.S., a day before the Erie Incident, by Ron Kalanark. It was the [color=#33FF33]Green type. Affiliated with nature and growth, it would be a nice present to someone fascinated by that kind of things. However, just by looking at the glowing "pulses" coming from the artifact, you could tell it was/it's dangerous. It was hidden somewhere, to be found by Kalan Yamato 2 years later.
The second of these Artifacts was discovered, again, in 816 A.S., at the time of the Erie Incident, by Sarah Andrews. After the escape from the capturers, the Red type was inside the Prototype Spatial. Colour of blood, life and love. She kept it and used it as a necklace ever since. Because of it's discreet design, nobody ever suspected that such an innocent thing as a necklace could be anything "fatally harmful for mankind".
Yet the third of these Artifacts was discovered this year, this time in 817 A.S., by a group of Outcasts. It was the Blue type, discovered near the Outcast Fighter graveyard. Peace, quiet, and the sound of water flowing, probably wasn't the Outcasts' best interest. It was sold to Jerry McVyper, the calmest within the Outcasts. Or, at least, close to such status.
However, the Black type was discovered as early as 803 A.S., by Achmed Afaik, at Planet Toledo. Reflecting darkness, emptiness and evil. Fits Achmed's personality perfectly. However, at late 818 A.S., Achmed Afaik dissapeared, and the whereabouts of the artifact are unknown.
Many rumours spark about these strange objects. It is said that, if all the four artifacts are put together, they will form a flower-like object, and the ones who had these artifacts, should they work together, would be rewarded with strange, psychokinetic powers. These are just rumours, of course. There is no evidence to support these theories.
Very recently, each wielder of these artifacts received something that we, the humans, used an insanely long time ago: Cassette Tapes.
Today, we very rarely, if never, use Cassette Tapes. There aren't any Cassette players in stores or anything. That's why each wielder conveniently received a Cassette player. It is odd, strange and a bit awkward, but in such a large Universe we live in, anything is possible.
The content in the Cassette Tapes is just a person speaking out numbers, but each tape has a different number scheme. So, the message within the tapes is encrypted and needs to be put in order. Unfourtanetly, the fourth Tape is nowhere to be found, due to the dissapearence of Achmed Afaik. So, the message cannot be fully decrypted.
